Assemblage is basically the three-dimensional cousin of collage. The origin of the word (in its artistic sense) can be traced back to the early 1950s, when Jean Dubuffet created a series of collages of butterfly wings, which he titled assemblages d’empreintes. Dubuffet wasn’t the earliest assemblage artist, however both Marcel Duchamp and Pablo Picasso had been working with found objects for several years prior to Dubuffet.
